Abstract
The invention belongs to the technical field of refractory materials and particularly relates to a steelmaking tundish guard plate and a castable therefor. The castable for the steelmaking tundish guard plate disclosed herein is made by mixing, by weight, 50-70% of wasted magnesia-chrome brick particles, 20-30% of sintered magnesium sand, 2-5% of silica powder, 5-8% of aluminum powder, 2-5% of silicon carbide, and 1-2% of stainless steel fiber. As the recycled wasted magnesia-chrome brick is used as a main material, wasted secondary resources are made full use and good environment-protection benefit is achieved; meanwhile, compared with the same industry where fused magnesite is used directly as main aggregate, the guard plate of the invention has improved slag resistance and prolonged life, and has greatly reduced production cost and significant economic and social benefits.

Technical field
The invention belongs to technical field of refractory materials, and in particular to one kind is made steel tundish backplate and its uses castable.
Background technology
After 20 century 70s, the continuous casting process of iron and steel steel-making enterprise is rapidly developed, and is characterized in process speed
Degree is fast, and investment is concentrated, and technology is gradually improved.Whole world continuous casting ratio is only 5.6% within 1970, and to nineteen ninety global continuous casting
62.4% is reached than, the continuous casting ratio of some industrially developed country has exceeded 95%.In recent years in the world many steel mills are real
Sequence casting production is showed.Compared with traditional steel-making die casting process, continuous casting has raising recovery rate of iron and reduces energy expenditure
Superiority, and reduce metals resources and energy consumption meet sustainable development requirement.The realization of sequence casting makes steel-making
Production process simplifies, and flow process shortens, and production efficiency is significantly improved.
Tundish is the intermediate link of STEELMAKING PRODUCTION flow process, and is the connecting points that continuous operation is turned to by intermittently operated.
Tundish is the important ring for improving output of steel and quality as metallurgical reaction, no matter being smoothed out for continuous casting operation,
Or for guarantee molten steel quality suits the requirements, the effect of tundish is very important.Because bakie working lining directly with
Steel contacts, it is desirable to which bakie working lining can reduce the field trash in molten steel, the degree of purity of raising molten steel, and resistance to molten steel and melt
The erosion of slag, makes the time of continuous-casting steel pouring as long as possible, and tundish reduces labor intensity with rear easy disintegration.
Backplate is to use prefabricated component made by castable refractory, and it is mainly used in, and tundish is spacious to be poured and long-time pouring technology,
Tundish impact and impact zone opposing regions are acted on, plays a part of to protect bakie working lining.Pour opening and pour for a long time
During note, tundish impact area domain and shock zone opposing regions are washed away by molten steel and corrode the most serious with slag.
Traditional backplate is directly compared using fused magnesite for main aggregate, and its slag resistance is poor and the life-span is not high, production
Cost is larger.
